node-forge is vulnerable to ASN.1 OID Integer Truncation

CVE-2025-66030 / GHSA-65ch-62r8-g69g

More information

Details

Summary

MITRE-Formatted CVE Description
An Integer Overflow (CWE-190) vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures containing OIDs with oversized arcs. These arcs may be decoded as smaller, trusted OIDs due to 32-bit bitwise truncation, enabling the bypass of downstream OID-based security decisions.

Description

An ASN.1 OID Integer Truncation vulnerability exists in the node-forge asn1.derToOid function within forge/lib/asn1.js. OID components are decoded using JavaScript's bitwise left-shift operator (<<), which forcibly casts values to 32-bit signed integers. Consequently, if an attacker provides a mathematically unique, very large OID arc integer exceeding $2^{31}-1$, the value silently overflows and wraps around rather than throwing an error.

Impact

This vulnerability allows a specially crafted ASN.1 object to spoof an OID, where a malicious certificate with a massive, invalid OID is misinterpreted by the library as a trusted, standard OID, potentially bypassing security controls.

This vulnerability impacts the asn1.derToOid function in node-forge before patched version 1.3.2.

Any downstream application using this component is impacted. This component may be leveraged by downstream applications in ways that enables partial compromise of integrity, leading to potential availability and confidentiality compromises.

node-forge has an Interpretation Conflict vulnerability via its ASN.1 Validator Desynchronization

CVE-2025-12816 / GHSA-5gfm-wpxj-wjgq

More information

Details

Summary

CVE-2025-12816 has been reserved by CERT/CC

Description
An Interpretation Conflict (CWE-436) vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft ASN.1 structures to desynchronize schema validations, yielding a semantic divergence that may bypass downstream cryptographic verifications and security decisions.

Details

A critical ASN.1 validation bypass vulnerability exists in the node-forge asn1.validate function within forge/lib/asn1.js. ASN.1 is a schema language that defines data structures, like the typed record schemas used in X.509, PKCS#7, PKCS#12, etc. DER (Distinguished Encoding Rules), a strict binary encoding of ASN.1, is what cryptographic code expects when verifying signatures, and the exact bytes and structure must match the schema used to compute and verify the signature. After deserializing DER, Forge uses static ASN.1 validation schemas to locate the signed data or public key, compute digests over the exact bytes required, and feed digest and signature fields into cryptographic primitives.

This vulnerability allows a specially crafted ASN.1 object to desynchronize the validator on optional boundaries, causing a malformed optional field to be semantically reinterpreted as the subsequent mandatory structure. This manifests as logic bypasses in cryptographic algorithms and protocols with optional security features (such as PKCS#12, where MACs are treated as absent) and semantic interpretation conflicts in strict protocols (such as X.509, where fields are read as the wrong type).

Impact

This flaw allows an attacker to desynchronize the validator, allowing critical components like digital signatures or integrity checks to be skipped or validated against attacker-controlled data.

This vulnerability impacts the ans1.validate function in node-forge before patched version 1.3.2.
https://github.com/digitalbazaar/forge/blob/main/lib/asn1.js.

The following components in node-forge are impacted.
lib/asn1.js
lib/x509.js
lib/pkcs12.js
lib/pkcs7.js
lib/rsa.js
lib/pbe.js
lib/ed25519.js

Any downstream application using these components is impacted.

These components may be leveraged by downstream applications in ways that enable full compromise of integrity, leading to potential availability and confidentiality compromises.

Severity

  • CVSS Score: 8.7 / 10 (High)
  • Vector String: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N

node-forge has ASN.1 Unbounded Recursion

CVE-2025-66031 / GHSA-554w-wpv2-vw27

More information

Details

Summary

An Uncontrolled Recursion (CWE-674) vulnerability in node-forge versions 1.3.1 and below enables remote, unauthenticated attackers to craft deep ASN.1 structures that trigger unbounded recursive parsing. This leads to a Denial-of-Service (DoS) via stack exhaustion when parsing untrusted DER inputs.

Details

An ASN.1 Denial of Service (Dos) vulnerability exists in the node-forge asn1.fromDer function within forge/lib/asn1.js. The ASN.1 DER parser implementation (_fromDer) recurses for every constructed ASN.1 value (SEQUENCE, SET, etc.) and lacks a guard limiting recursion depth. An attacker can craft a small DER blob containing a very large nesting depth of constructed TLVs which causes the Node.js V8 engine to exhaust its call stack and throw RangeError: Maximum call stack size exceeded, crashing or incapacitating the process handling the parse. This is a remote, low-cost Denial-of-Service against applications that parse untrusted ASN.1 objects.

Impact

This vulnerability enables an unauthenticated attacker to reliably crash a server or client using node-forge for TLS connections or certificate parsing.

This vulnerability impacts the ans1.fromDer function in node-forge before patched version 1.3.2.

Any downstream application using this component is impacted. These components may be leveraged by downstream applications in ways that enable full compromise of availability.
